PurposeTo study long term visual and refractive outcomes and complications in eyes with anterior chamber intraocular lens (ACIOL) implantationMethodsData of patients who underwent primary and secondary ACIOL implantation at L V Prasad Eye Institute, Bhubaneswar between 2011-2020 was collected, including details of post-operative visits. For analysis, sample was divided into: group Ia (primary ACIOL in cases without risk factors, n=104); group Ib (primary ACIOL in cases with pre-existing risk

Mean pre-operative and last visit corrected distance visual acuity were 1.65±0.79 and 0.49±0.65 logMAR units in group Ia (p<0.001), and 1.46±0.74 and 0.52±0.72 logMAR units in group Ib (p<0.001). The mean spherical equivalent (MSE) for last refraction was -0.37 ± 1.05 dioptres (D) and -0.57 ± 1.04 D in groups I and II, respectively. Of 76 eyes in which addition of 2.5 D (over the near emmetropic posterior chamber intraocular lens power) was taken for ACIOL, 40 (52.6%) had MSE within ±0.5 D. Most common complications were transient corneal edema and anterior chamber reaction. Eyes on anti-glaucoma medications at last visit were eight (7.7%), 15 (30.6%), and two (5.0%) in groups Ia, Ib, and II respectively.ConclusionsWe observed that ACIOLs have good visual and refractive outcomes. Raised IOP is a concern in eyes with pseudoexfoliation, but can be managed with close monitoring. Hence ACIOL can be a good option for managing aphakia after cataract surgery.
